The PDF contains a heuristic firing for CVE-2008-2551, indicating an exploit for a downloader. An embedded URL points to a potential executable payload. The document body was not sufficiently readable to determine a specific lure, but the presence of an exploit and a downloadable executable strongly suggests a malicious intent to compromise the user's system.
